Abstract: Objective To investigate the infection situation of intestinal nematodes and knowledge about the prevention and control of intestinal nematodiasis， so as to explore the effective control measures in Jingjiang City. Methods The towns where more floating people lived were randomly selected and the infection situation of intestinal nematodes was investigated with Kato?Katz method， and the residents’ awareness of the prevention and control of nematodiasis was surveyed with questionnaires. Results From 2013 to 2015， totally 4 555 local residents and 2 278 floating people were investigated in Jingjiang City. The infection rate of intestinal nematodes was 0.29% （13 cases） in the local people， while the rate was 0.75% （17 cases） in the floating people， and the difference was significant （[χ2]= 7.380， P < 0.01）. The differences of the intestinal nematode infection rates between sexes in both local residents and floating people were not significant （[χ2]= 0.010， 0.048， both P > 0.05）. The awareness rate of intestinal nematodiasis prevention and control of the local residents was significantly higher than that of the floating people （[χ2] = 9.649?164.533， all P < 0.01）. Conclusion The floating people is the focus of intestinal nematodiasis control， and the health education of ancylostomiasis control should be strengthened in Jingjiang City.

摘要： 目的 调查靖江市居民肠道线虫感染情况及对其认知现状，探索有效控制肠道线虫病的措施。 方法 在靖江市随机抽取流动人口相对集中的乡镇，以Kato?Katz法检查居民肠道线虫病感染情况，问卷调查防病知识知晓率和卫生行为正确率。 结果 2013-2015年共计在靖江市分别调查本地居民和流动人口4 555人和2 278人。本地居民肠道线虫病感染率为0.29%（13例），流动人口为0.75%（17例），差异有统计学意义（[χ2] = 7.380，P < 0.01）。本地居民和流动人口性别间肠道线虫病感染率差异均无统计学意义（[χ2]= 0.010、0.048，P均 > 0.05）。本地居民对肠道线虫病的知晓率高于流动人口，差异有统计学意义（[χ2]= 9.649～164.533，P均 < 0.01）。 结论 流动人口是靖江市肠道线虫病的重点防控对象，应对其加强综合干预；健康教育中应加强钩虫病防治相关知识的宣传。
